英文摘要	We have investigated the dynamic behaviour of the magnetization of a hydrogen-bonding linked Co(II) 1D supramolecular coordination polymer. In the structure, two different mononuclear Co(II) species are linked by O-H center dot center dot center dot N hydrogen bonding through coordinated H2O and [GRAPHICS] . Field-induced slow magnetic relaxation effect is observed and the anisotropy energy barrier is 33K. Ab initio calculations reveal that Co(II) ion in [Co(bpm)(2)(N-3)(2)] species is uniaxial anisotropic with a negative axial zero-field splitting parameter of D=-82.4cm(-1). The Co(II) ion in [Co(bpm)(2)(H2O)(2)](2+) species, however, is easy-plane anisotropic with a positive D and negative E value (D=46.3cm(-1), E=-7.8cm(-1)). This is an interesting complex in which slow magnetic relaxation stems from the combination contribution of uniaxial anisotropy and easy plane anisotropy.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000350879800012&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Multidisciplinary; SCI(E); 6; ARTICLE; yyzhu@hfut.edu.cn; zqwu@hfut.edu.cn; zhangyiquan@njnu.edu.cn; 5-6,SI; 401-406; 27
